PURPOSE:To stepwise control the position of a rotary damper by providing the function for automatically and manually selecting one among the blowing-out modes for a rotary damper such as vent, heater, by-level, etc. onto the captioned apparatus. CONSTITUTION:The operation controller for an air conditioner 2 for car is equipped with a reversible revolution type d.c. motor 1 for driving a rotary damper 3, and manual switches 15-18 having a plurality of contact-points for selecting one of a plurality of air conditioning modes for determining the direction of electric conduction of the motor 1 and a position detecting switch 20 for position feedback which is opened and closed according to the actual position of the damper 3 are combined Said detecting switch 20 is operated not only by the manual switches 15-18 but also in the combination with a interlocked switch 31 interlocked with the control state of an automatic temperature control mechanism. In other words, the switch 31 is connected in parallel to the switches 15-18, and the switch 31 controls the electric conduction for the motor 1 in cooperation with the detection switch 20. |
